Intracerebroventricular and Intravascular Injection of Viral Particles and Fluorescent Microbeads into the Neonatal Brain05:51

Intracerebroventricular and Intravascular Injection of Viral Particles and Fluorescent Microbeads into the Neonatal Brain

20.3K
Here, we describe a simple method of intracerebroventricular and intravascular injection of viral particles or fluorescent microbeads into the neonatal mouse brain. The localization pattern of the virus and nanoparticles could be detected by microscopic evaluation or by in situ hybridization.

A Rapid and Specific Microplate Assay for the Determination of Intra- and Extracellular Ascorbate in Cultured Cells

13.9K
Ascorbate plays numerous important roles in cellular metabolism, many of which have only come to light in recent years. Here we describe a medium-throughput, specific and inexpensive microplate assay for the determination of both intra- and extracellular ascorbate in cell culture.

Direct Intraventricular Delivery of Drugs to the Rodent Central Nervous System

61.6K
We describe a method to target drugs to the central nervous system by either implanting a catheter or performing a bolus injection into the right lateral ventricle in mice. We focus specifically on the delivery of antisense oligonucleotides. This technique is readily adaptable to other drugs and to...

    Area of Science:

    • Cardiology
    • Cardiac Surgery
    • Medical Imaging

    Background:

    • Intraoperative assessment of cardiac structures and surgical correction is crucial for patient outcomes.
    • The utility of real-time imaging during cardiac surgery can significantly impact surgical strategy and decision-making.

    Purpose of the Study:

    • To evaluate the usefulness of intraoperative epicardial two-dimensional (2D) echocardiography in a large cohort of cardiac surgery patients.
    • To determine the impact of this imaging modality on diagnosis, surgical management, and assessment of surgical correction.

    Main Methods:

    • A prospective evaluation of 200 patients undergoing cardiac surgery.
    • Utilized a commercially available 5 MHz mechanical sector scanner with the probe placed in a sterile plastic bag on the exposed heart.
    • Surgeons interpreted the echocardiographic images in real-time.

    Main Results:

    • New, unsuspected diagnoses were made in 7 patients.
    • Additional morphological information influencing surgical management was obtained in 68 patients, impacting decisions in 32.
    • Crucial information for immediate reoperation decisions was provided in 16 patients.
    • Expected results of surgical correction were confirmed in 184 patients.

    Conclusions:

    • Intraoperative epicardial 2D echocardiography, when performed by experienced surgeons, yields critical information for surgical management.
    • This technique serves as a valuable adjunct for immediate decision-making in cardiac surgery, contributing to optimal results.
